As his world is decimated, Broly shields himself and his father using an Energy Shield, which allows both Broly and Paragus to survive without air

I was just going off of what the wiki says:

As his world is decimated, Broly shields himself and his father using an Energy Shield, which allows both Broly and Paragus to survive without air

That is an error on their part. Frieza blew up Planet Vegeta when Broly was just days old. He made the shield to survive the explosion. As I said, it shows Broly and his father flying through space without any shields or any equipment.

Adding to something Sirmethos already, mostly ably, stated: Superman is known to blow away a planet devouring fulyl expanded Braniac with one blow when powered by the sun's core. He will do just that, if he has to in this fight: fly right through the sun. In that, his durability, his speed, his strength, increases manifold. That is not even funny, when we consider stats and actual figures. I am not saying that it will be a 'ham n' egger', but it will happen this way, if it has to.

Simply put: Superman's level headed, in proximity to a solar source, and better experienced. There will be a battle, albiet one that will end with Superman winning here.

um--well, supes can't destroy galaxies in the blink of an eye--broly is probably the most powerful being in any mythos if anyone would watch the first movie. i can't think of anything or anyone that could beat him.

AGH!!! NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! See what happens when I vote to rate???!!! I gave Superman a win!!! Oh, the shame. THE SHAME!!!
